Using a few milliamps of current to stimulate your brain - a thinking cap. This subreddit is for anyone interested in discussing the use, construction, and theory of noninvasive electrical brain stimulators.

1.Using a tDCS device safely requires (at minimum) a basic understanding of Ohm's law and its implications. If you don't understand why you can be killed by a 9V battery, you probably shouldn't be tDCSing yourself.

2.tDCS (and related technologies) are experimental. In most cases, there are options available for treating medical and psychiatric problems which have more demonstrated efficacy and safety than tDCS. If you are concerned about some aspect of your mental or physical health, please consult a medical professional before using tDCS.

Nothing posted here should be considered valid medical advice, everything is discussed in a strictly scientific context, if you choose to use a tDCS machine, it is your responsibility to ensure that it works correctly and your usage is within reasonable limits.

If you are using a device you bought which is malfunctioning, please submit a report to MedWatch. They can do a lot more than we can to investigate the problem.
